WILNER E. JOHNSON, OF BROOKLYN, NEW YORK, ASSIGNOR TO MEGOSIN COMPANY, INC., A CORPORATION OF NEW YORK.

HAND-BRAKE.

To all 'whom it may concer/n.

Be it known that I, WILNER E. JOHNSON, a citizen of the United States, and residing in the borough of Brooklyn, county of Kings, and State of New York, have invented certain new and useful Improvements in Hand-Brakes, of which the following is a full and clear specification.

This invention relates to hand brakes for railway or similar vehicles and has for its primary object to provide an improved construction, combination and arrangement of parts in a brake, in virtue of which said parts are normally disposed within small compass and out of the way of passengers or others that may be passing through the car.

More especially, the invention is applicable to street railway cars or cars which handle crowds that are getting olf and on at frequently recurring intervals. As a preferred embodiment of my invention, I have shown its adaptation to a subway car in which the column between spaced doorways of said car is employed to mount the brake-operating mechanism.' 1

Further and more specific objects vof invention will appear in the specification and claims, reference being had to the accompanying drawings in which,

Figure 1 is a side elevation of the preferred embodiment of my invention, parts beingl broken away and parts shown in section; Fig. 2 is a top plan view of the same, parts being broken away and parts shown in section; Fig. 3 is a fragmentary section on the lineIII-III, Fig. 2, parts being shown in elevation; Fig. 4 is an end elevation taken from the right of Fig. 1.

In the preferred embodiment shown in the drawings,1 the brake-sta 1 is suitably mounted with respect to the floor 2 of the car, and carries adjacent the Hoor 2 a ratchet wheel 3 which is adapted' to be held by a pawl 4 mounted on a stud 5. The upper end of the brake stal 1 is reduced in diameter somewhat and provided with facets 6 upon which is removably seated a sleeve 7 which is similarly formed, so that relative rot-ation betwen these parts will not occur. The periphery of the sleeve 7 is provided with ratchet teeth 8 into engagement with which the pawl 9 moved when the hand lever, to be hereinafter referred to, is drawn out Specification of Letters Patent.

Wardly from the wall of the car. The sub- Iway car, of which fragmentary portions are indicated on the drawings, is provided with lateral doorways 10, which are spaced longitudinally of the car for the accommodation of doors 11. Interposed between the doors 11 is a hollow sheet metal column 12, in the inner wall of which. is provided an opening in which is mounted a recessed portion 13 of a plate provided with flanges 14 secured to said inner wall around the edges of said opening. As shown best in Figs. 1 and 3, the recessed plate just referred to is provided with vertically spaced bearings 15 within which the upper end of the brakestaff 1 is journaled. Suitablemeans for operatably connecting the hand lever to the brake staff are provided by constructing the hand lever to comprise housing 16, which incloses the operating connection between the hand lever and thebrake-statf, forked branches 17 which project from said housing 16, and a handle grip 18 which is carried be? tween the branches 17. Vertically spaced bosses 19 on the upper and lower walls of the housing 16, serve to pivotally mount the hub portion 20 of a ratchet pawl 9, said pawl being provided with a tail piece 21 which is deflected outwardly, as shown in Fig.A 2. Threaded into the inner wall of the recessed plate 13, is an abutment 22 against which the tail piece 21 is thrown when the hand 1ever is in its extreme position adjacent the inner wall of the car, as shown in full lines in Fig. 2. Under this condition, the pawl 9 is retracted from the ratchet 8. Interposed between the tail piece 21 and the opposite lateral wall of the housing 16, is a spring 23 which normally tends to hold the pawl 9 into engagement with the teeth 8. In consequence, whenever the hand lever is moved into the position shown in dotted lines in Fig. 2, the pawl 9 engages the ratchet 8 and imparts a clockwise rotation to the brakestaff 1. By an inspection of Fi 2, it will be noted that the outer end of t e housing 16 is suitably formed to provide a nose or corner 24, which is adapted to be releasably engaged by a latch 25 which is pivotally -g hand lever againstfthe inner Wall of the car when not in use. Y

.The method of operation of my improved hand'brake Will now be readily understood and briefly described is as'follovvs: When it is desired to brake the car, the operator by grasping the grip 18 moves the hand lever in a clockwise direction, `according to Fig. 2. As lsaid lever swings into" the position indicated in dotted lines in Fig. 2, the pavvl 9 is released from engagement With the abutment 22, the spring 23' forcing it Vinto connection With the ratchet 8 and iin ar'ting a clockwise rotation to the. brake-'sta' 1. This action is repeated as many tiines as desired. When sufficient power 'has' been applied to the brakes the return if the, hand lever into position sho'vv'n infll lines in'v Fig. 2, forces' the pavvl 9 into vp ositio'n tor'elease the ratchet Wheel 8 and inak'esitpossiblev to4 release the Q brake-staff I disengaging the paWl 4 from the ratchet vvhe'el 3. F rom 'an inspection of Fig. 2, it will be that 'the housing 16 projects laterally on the-side adjacent to the inner' wall of the car' and when in the posin tion Ashovvn in full lines in Fig 2, eX-v tends' into vthev recess in the plate 13. This' construction is c'olmpact and disposes of the moi/'in'l partsof the'ratchet connection and hand ever attachments iii-such a Way as to occupy veryY little spaee, ivhile at the same' timep'rdvidiiiga simple antenati@ Constructionfor releasing' thev hand lever from the brake-staff. nine end diene-ii braking action. Furthermore, theiatc'h 25 serves to retainthe hand lever a position in Which it does not encumber tlievs'pace of the' car'.
